  FIG. 3 is a block diagram illustrating software configurations of the client terminals (101, 102) and the file servers (103, 104) illustrated in FIG. Reference numeral 301 denotes server software of the file server. The server software is executed by the file server (103, 104), receives each request from the client (101, 102) via the network 110, and inputs / outputs document data of the file server. A communication unit 302 receives a request from a client application (to be described later), instructs the data management unit 303 (to be described later) to process document data according to the content of the request, and returns a processing result response to the client via the network. To do.

  A data management unit 303 inputs and outputs document data to a document database 304 described later in response to an instruction from the communication unit 302. A document database 304 manages document data storage and attached information such as index data related to each document data. Reference numeral 305 denotes a document management application. The document management application is installed on the client and, in response to a request from the user, communicates with the server software to access the document data managed by the file server and the document data managed by the OS file system. Various document operations can be performed.

  A UI unit 306 receives the construction of the user interface shown in FIG. 4 and various input operations from the user, and instructs the document management processing unit 307 described later to perform corresponding processing. A document management processing unit 307 executes various operations such as document list display, search, move, and copy in accordance with instructions from the UI unit 306. A data access unit 308 transmits a request corresponding to various document operations executed by the document management processing unit 307 to the server software via the network, and processes a response returned from the server software.

FIG. 4 shows an example of a user interface of the document management application.
Reference numeral 401 denotes a main window. Reference numeral 402 denotes a navigation pane for navigating access to a file server or OS file system managed by the document management application. In the navigation pane, storage areas of file servers and OS file systems are displayed in a tree structure, and the storage areas can be accessed in response to user instructions.

  HDD1 and HDD2 in the figure indicate the storage area of the OS file system, and XX_Library (403) indicates the storage area of the file server. Reference numeral 404 denotes a storage area selected by the user, and shows a state in which the Company folder of XX_Library is selected. Reference numeral 405 denotes a file list pane for displaying a list of files and folders stored in the storage area selected in the navigation pane 402. The figure shows an example in which the document data of SampleFile1, SampleFile2, SampleFile3, and SampleFile4 and the folder of Division1 are displayed in the selected Company folder.

  The document management application communicates with the server software at regular intervals to update the list display in the file list pane to the latest status, requests information acquisition for the list display in the file list pane, and responds to the response from the server software. In response, the list display in the file list pane is updated. Since communication with the server software is performed at regular intervals, when a large number of clients are connected to the server, the file server becomes heavily loaded, and a response is delayed. Therefore, in the document management application, it is possible to set whether or not to automatically update the regular interval of the list display of the file list pane described above and the time of the regular interval.

  FIG. 5 shows an example of setting data for updating the list display of the file list of the document management application. Setting data for updating the list display of the file list pane is data stored in the HDD 205, and the document management processing unit 307 controls writing and reading of data in accordance with an instruction from the UI unit 306 of the document management application. To do. “Polling Monitor” 501 indicates whether to automatically update the list display in the file list pane. “Polling Interval” 502 indicates the setting of a regular interval time.

  The setting in the figure shows a setting for updating the list display in the file list pane at intervals of 10 seconds. Reference numeral 406 denotes an address bar that displays the location (for example, folder path or URL) of the storage area selected in the navigation pane 402. Reference numeral 407 denotes a button for minimizing the main window of the document management application. Reference numeral 408 denotes a button for hiding the main window of the document management application. The above-described non-display indicates a state in which the main window is hidden from the OS desktop window and the processing of the document management application continues to be executed in the background.

  The document management application may manage the display state (minimization or non-display) of the main window with the temporary memory (RAM 203) during execution of the application, or with the setting data. FIG. 6 shows an example of setting data for managing the display state of the main window of the document management application. The setting data for managing the display state of the main window is data stored in the HDD 205, and the document management processing unit 307 controls writing and reading of data in accordance with an instruction from the UI unit 306 of the document management application.

  “Visible” 601 indicates whether the main window is hidden or not. “Minimization” 602 indicates whether the main window is minimized. In the figure, the main window shows a minimized setting.

  FIG. 7 is a flowchart showing automatic update processing of the list display of the file list pane of the document management application. Each processing step will be described. S701 is a processing step of determining whether or not the setting for automatically updating the list display of the file list pane is made. The document management application accesses the setting data (FIG. 5) described above, and if “Polling Monitor” (501) is set to be automatically updated, the process proceeds to S702. If it is not set to be automatically updated, the process of this flowchart is terminated. S702 is a processing step for acquiring the display state of the main window.

  The document management application obtains the display state of the main window by accessing the setting data (FIG. 6) described above. S703 is a processing step for determining whether or not the main window is in a non-display state. If “Visible” (601) of the setting data (FIG. 6) is set to non-display, the process proceeds to S707. If “Visible” is not set to non-display, the process proceeds to S704. S704 is a processing step for determining whether or not the main window is in a minimized state.

  If “Minimization” (602) in the setting data (FIG. 6) is set to minimize, the process proceeds to S707. If “Minimization” (602) is not set to minimize, the process proceeds to S705. Step S705 is a processing step in which the document management application requests the server software to acquire the list information of documents and folders to be displayed on the file list pane in order to update the list display on the file list pane. The document management processing unit of the document management application transmits a request for acquiring the document / folder list information together with the information of the address 406 displayed in the file list pane to the server software via the data access unit 308. .

  Step S706 is a processing step of processing the server software response to update the list display in the file list pane. Upon receiving the request transmitted in S705, the server software communication processing unit 302 acquires the document / folder list information at the specified address via the data management unit 303, and sends a result response to the document management application. Send. The document management application receives the response at the data access unit 308, and updates the list display in the file list pane based on the document / folder list information acquired by the document management processing unit 307.

  S707 is a processing step that waits until the next automatic update is executed. The document management processing unit 307 of the document management application performs an automatic update interval time wait process indicated by “Polling Interval” (502) in the setting data (FIG. 5), and the process advances to step S701.

  By executing the processing steps shown in this flowchart, when the main window of the document management application is minimized or hidden, the process of automatically updating the list display in the file list pane is not performed, so usability It is possible to reduce the load on the file server without lowering the server. In this embodiment, minimization and non-display of the main window are taken as an example, but other display states that can obtain the same effect (for example, the window of another application is active and the main window of the document management application is displayed). May be invisible).
